I'm a big fan of your works and follow you in DA and Y-gallery. I wanted to say thougt, that in my humble opinion, I think that the price is too much for the comic. An 11pages comic costing $13,00 seems too high. I'm not telling you're not good; on the contrary. All I'm saying is that when most average comic books cost about $10-14 and have 36-48+ pages, I think that $12,99 is a bit too much for 11 pages + cover. Not to mention that you can provide it in PDF format which has no printing costs.

I think a more logic price, like $5 or $6 would make it more appealing for purchase/download, and would lead in more sales.
